Why PDF files can be very large
PDF files with text are usually small. Only the embedded fonts are there, taking up the most space. In files with images it will look different. There are images that will take up too much space if you are not careful when creating the PDF. If there are many images in the PDF, than the PDF size may increase by several megabytes. You shouldn’t send very large files via email, because there is no guarantee here that the recipient can receive a file that is so big.
PDF24 Compress can shrink your PDF files
PDF24 Compress is a part of PDF24 Creator. This small tool can significantly reduce your PDF files that have images by compressing your images in the PDF. Often this reduction and compression of images are not noticed in your final PDF file, but your PDF will become significantly smaller. First install the current PDF24 Creator. Then start PDF24 Compress. Pull all your PDF files that you need to shrink in the file list. The program shows the current size and the size after reduction. There may sometimes be a very large difference. Finely-tune the process by adjusting a few parameters. The default setting has good parameters that make the files sufficient for viewing the PDF on your screen. Save all your PDF files after this.
With PDF24 Compress you can shrink many PDF files at once. You only need to add all your files to the list. The reduction is completed for all documents in the list. For each file the size differences will be displayed.
